Hydrogen’s influence on tungsten-nickel-iron alloy performance—through hydrogen embrittlement, conductivity degradation, and hydrogen retention—can reduce material reliability. However, controlling hydrogen content and enhancing performance can be achieved through alloy design and surface engineering.

Tungsten-nickel-iron alloy boasts high density, high tensile strength, excellent radiation absorption, and good processability, making it widely applicable in aerospace counterweights, armor-piercing projectile cores, nuclear radiation shielding, and medical equipment protection. Beyond tungsten content, powder characteristics, production processes, and process parameters, the nickel-iron ratio is another key factor influencing its performance.

Tungsten-nickel-iron alloy (W-Ni-Fe alloy) is a high-density alloy with tungsten as its matrix, allowing for a balance of density, strength, toughness, and cost through the adjustment of the nickel-iron ratio or the addition of trace elements. It is widely used in aerospace, defense, medical devices, and other fields. The alloy’s material composition includes tungsten, nickel, iron, carbon, and other elements.

Tungsten is the core component of tungsten-nickel-iron alloy, imparting exceptional counterweight performance through its high density of 19.35 g/cm³. It also enhances the alloy’s strength and hardness via solid-solution strengthening and particle dispersion strengthening, while optimizing its radiation absorption capacity, making it an ideal choice for high-performance shielding materials.
